Features
The DPX 5080 is a fully integrated imagesetter and processor that produces
polyester printing plates. A film handling option is available.
The imagesetter unit is a high-precision, 2-up, internal drum imagesetter
driven by Purup-Eskofot’s RipMate software RIP and associated software. The
processor unit is 100% computer-controlled and -monitored.
Among the advantages of the DPX 5080 are:
• An extremely simple and efficient media path.
• A wide range of output resolutions (from 900 to 3600 dpi) for flexibility in
meeting the speed and quality demands of each individual job.
• An unusually wide range of spot sizes that are automatically optimized to
the chosen output resolution.
• The ability to image screen rulings up to 300 lpi (118 lines per cm).
• Compact size and low noise level to fit into any working environment.
• User-friendly and service-friendly design.
Available options
The DPX 5080 can be driven by RipMate Basic, an entry-level RIP tailored to the
needs of smaller prepress installations, or by RipMate Extended, which includes
multi-user spooling as well as the RipWatch module for remote queue control
and output surveillance.
RipMate Extended is required if you wish to add optional workflow
modules like InRIP OPI Manager, MediaSaver film packing and EasyTrap
InRIP trapping or advanced screening techniques such as Harlequin Dis-
persed (stochastic) Screening, Harlequin Chain Screening, and Harlequin
Micro Screening. Upgrades from RipMate Basic to RipMate Extended are
available.
A film handling option is available as a set that includes a take-up cassette,
an extra input cassette, a buffer module and a guide assembly.

Laser safety
The DPX 5080 is a Class I laser product and contains a laser which, however,
is totally shielded by the cabinet. When the cabinet is opened, the interlock
system automatically switches off the laser, and there is no risk of laser
radiation.
WARNING: Only authorized service personnel may override the interlock
system. The laser warning labels on both sides of the drum assembly are
intended for such personnel.

Operational description
The DPX 5080 has a very short, efficient media path, shown schematically
below.
Basic operation
1 • When a job is sent to the imagesetter or a “PRELOAD” command is
given, the feed rollers close on the plate just long enough to feed it to
the input rollers. The input rollers then pull the plate from the input
cassette and load it into the drum.
During plate loading, the carriage upon which the
optics unit is located moves to the middle of the drum.
At each end of the carriage, a semicircular guide hoop is
mounted. These guides support the plate during loading
and prevent it from falling onto the optics unit. Sensors
on the guides report an error to RipManager if the plate
is not properly loaded.

2 • The input and output rollers feed the plate all the way around the drum
and through the output module and hold the plate securely in place.
The input and output sensors monitor the position of
the plate and report an error to the RIP if the plate is not
properly loaded and positioned for exposure.
3 • The optics unit moves to the right-hand end of the drum and exposes
the plate, starting at the right and moving towards the left.
The plate is exposed by a laser which spins continuously
around a central spindle as the carriage moves along the
length of the drum. The carriage will only move as far as
necessary to expose the job, depending on the job parame-
ters, the format of the page, and its orientation in the drum.
4 • The input and output rollers then transfer the exposed plate through
the output guide into the conveyor.
At the same time, media for exposure of the next page
enters the drum.
5 • The knife in the output module cuts the plate and the conveyor passes
the plate to the processor.
Film handling option w. take-up cassette, buffer module and guide assembly
1 • When the optional take-up cassette for film is fitted, the media feed is
the same as for plates, except that the input rollers, output rollers and
buffer rollers transfer the exposed film from the drum into the take-up
cassette instead of the conveyor.
At the same time, film for exposure of the next page
enters the drum.
2 • When an “EJECT” command is given, the knife in the output module cuts
the film, and the buffer rollers pass the film to the take-up cassette.
The take-up cassette can then be removed and the film
can be developed in an external processor.

Processor service program
The processor service program monitors the built-in processor unit during
normal operation and displays the status, so the operator can check that
the DPX 5080 is running correctly.
The Processor Service window contains five sections: Busy, Warning,
Info,Error and Temperatures. When an item in any of the first four sections
is activated or relevant, the white box next to it becomes coloured. The
meanings of the various items are listed below.
BUSY (indicator box turns GREEN)
•Standby (Off) . . . . . . . .The processor is in standby mode.
•Feeding . . . . . . . . . . . . . .Media is entering the processor.
•Activator Temperature . .The heating element is on to keep the activator
temperature within +/– 2°C of the requested value.
